Aisle 17

If you're ever at your local home improvement store and you're
standing in the drop cloth aisle and you say, "You know, I really
don't think I need any of these. It's only going to be extra money up
front and I probably won't spill or splatter any paint because I'm
really careful," turn immediately and go directly to a sales associate
and say, "Dont ask any questions but please go ahead and slap me
because I'm not being smart right now."
